K mills The show ranges from december 2014 to may 2015. If they were from TLC (I wouldn't know) it was probably to have a test-shoot. Funny detail? The Festival also made a video of one of the numbers and put it on KZbin, but it was very low resolution, so couldn't use it. The TLC crew was present at several performances in 2015, but only very few shots were used in the series.
